Tech firms should make a digital key for police to unlock encrypted messages in ‘exceptional circumstances’ such as child abuse or terror cases, a senior Norfolk police officer has suggested to an inquiry.

Norfolk police chief constable Simon Bailey, the UK lead for child protection, said the tool would help UK authorities who are already stretched to capacity hunting online predators, the Independent Inquiry Into Child Sexual Abuse (IICSA) heard.

But Melissa Polinsky, a senior executive at Apple, told the inquiry any such key could be exploited by hackers to harvest the passwords, bank and medical details of hundreds of millions of people.

"I'd like to be in a position to have that conversation, because end-to-end encryption is going to make an already incredibly difficult task for myself, the National Crime Agency (NCA), so much harder."

Counsel to the inquiry Jacqueline Carey said: "[Ms Polinsky] is saying that can't be done yet, so how is it that law enforcement is going to try and get round in a different way the problem that end-to-end encryption poses?"

Mr Bailey replied: "I think there needs to be with these companies some form of key that would afford access, and a very clear understanding from all customers that sign up to the contract that that key to break the privacy would only ever be used in exceptional circumstances."

The inquiry heard of an "exponential growth" in referrals flagging suspected child abuse in the UK, and Mr Bailey said Britain is the third-biggest consumer of live-streamed child sex abuse in the world.

Figures show referrals have jumped in recent years - from 43,072 in 2016 to 82,109 in 2017 and 113,948 in 2018.

Mr Bailey said around 400 suspects are arrested, with around 500 children safeguarded per month in the UK - but forces were at "saturation point".

He added: "Levels of depravity that haven't been seen before are now being seen."
